Q: An industrial loom weaves 0.128 metres of cloth every second. Approximately, how many seconds will it take for the loom to weave 25 metres of cloth?
A. 178 B. 195
C. 204 D. 488

Answer and Explanation

Answer:195

Explanation:
Let the required time be x seconds. Then, More metres, more time ( Direct Proportion)

0.128 : 25 :: 1 : x
0.128 x x = 25 x 1

x =   25
     0.128

x = 25 x 1000
         128

x = 195.31
Required time = 195 sec (approximately)
